Abstract:Substantial improvements in fracture toughness(KIC) and bending strength(σbb) were obtained by incorporating 25%(volume fraction) of SiCW into tungsten tallings glass-ceramics matrix. The shape memory effect of the composite has been observed. The causes of SiC whisker toughening and reinforcing were discussed through microscopic analysis.
Key words: SiC whisker tungsten tailings glass-ceramics whisker toughening shape memory effect
